- Abstract
Objective To determine the effect of age on weight loss and weight loss maintenance in participants in the Weight Loss Maintenance trial (WLM). Design and Methods Secondary analysis of a randomized controlled trial of overweight/obese adults with CVD risk factors was conducted. Participants were 1685 adults with baseline BMI 25-45 kg m2 with hypertension and/or dyslipidemia. Those who lost at least 4kg in an initial 6-month behavioral weight loss intervention ( N = 1,032) were randomly assigned to a 30-month maintenance phase of self-directed control (SD), monthly personal counseling (PC), or unlimited access to an internet-based intervention (IT). Age groups were defined post-hoc and weight change was compared among age groups. Results Participants ≥60 years old initially lost more weight than younger individuals, and sustained greater weight loss in IT and PC but not in SD ( P value for trend 0.024, 0.002, and 0.36, respectively). Conclusions In WLM, adults age ≥60 years had greater initial weight loss and greater sustained weight loss over 3 years, compared to younger adults. Older adults had greater weight loss maintenance with either personal counseling or internet-based intervention. Future research should determine optimal implementation strategies and effects of weight loss on health outcomes in older adults.
